One of the first questions people ask when they start taking the gym seriously is: how should I split my workouts? Full body three times a week? Push/pull/legs? The classic chest-on-Monday bro split? There's no single right answer — but there is a best answer for you, depending on how often you train and what you're trying to achieve.
What Is a Workout Split?
A workout split is how you organize which muscle groups you train on which days. Instead of doing everything every session, most people divide their training across the week so each muscle group gets enough work and enough recovery.
The right split helps you train hard without burning out. The wrong one can leave muscles undertrained or overtrained — both of which slow your progress.
Full Body (3 Days Per Week)
Full body training means hitting every major muscle group in each session. It's ideal if you can only get to the gym 2–3 times per week. You'll typically pick one or two exercises per muscle group and keep the volume moderate.
Best for: Beginners, people with limited gym time, and anyone coming back after a break. Research consistently shows that full body routines produce great results for newer lifters because each muscle gets trained multiple times per week.
Upper/Lower (4 Days Per Week)
This split alternates between upper body days and lower body days — typically four sessions per week. It's a solid middle ground that gives you more volume per muscle group than full body while still hitting everything twice a week.
Best for: Intermediate lifters who want more training volume but still value simplicity. A typical schedule looks like: upper Monday, lower Tuesday, rest Wednesday, upper Thursday, lower Friday.
Push/Pull/Legs (5–6 Days Per Week)
PPL splits your training into pushing muscles (chest, shoulders, triceps), pulling muscles (back, biceps), and legs. You can run it once per week across three days, or twice per week across six days for more volume.
Best for: Intermediate to advanced lifters who want to focus on individual muscle groups with higher volume. The six-day version is popular among bodybuilders because each muscle gets trained twice per week with plenty of exercises.
The Bro Split (5 Days Per Week)
The classic bodybuilding split dedicates one day to each muscle group: chest day, back day, shoulder day, leg day, arm day. Each muscle only gets trained once per week, but with high volume in that single session.
Best for: Advanced lifters who can handle high-volume sessions and want to focus on bringing up specific body parts. For most people, though, hitting each muscle twice per week produces better results than once — so consider this only if you have a specific reason for it.
How to Pick the Right Split
The best workout split is the one you'll actually stick to. Here's a simple decision framework:
- 2–3 days per week: Full body
- 4 days per week: Upper/lower
- 5–6 days per week: Push/pull/legs
Your schedule matters more than the "optimal" split. Training three days per week with a full body routine will beat a six-day PPL split that you only manage to do half the time. Consistency is the biggest factor in long-term results.
Tracking Your Split
Once you've chosen a split, the next challenge is keeping track of your exercises, weights, and progression across different training days. A few apps that make this easier:
- PR AI — Lets you organize workouts by training day and uses AI to recommend when to increase weight based on your logged performance across sessions.
- Strong — A clean workout logger where you can set up routines for each day of your split and track progress over time.
- Hevy — Workout tracker with a social component. Good for following friends' routines and getting ideas for your own split.
The Bottom Line
Don't overthink your workout split. Match it to how many days you can realistically train, pick exercises that target each muscle group, and focus on progressing over time. The best program is the one you follow consistently — and if your current split isn't working with your schedule, it's worth switching to one that does.
